Please stop inheriting the box-model. The supposed use-case for that is extremely out-dated, inheritance doesn't really help, and it actively makes real box-sizing use-cases more difficult! This #CSS best practice was never the best to begin with: www.oddbird.net/2025/09/04/b...

I've never _not_ seen border-box inherit, and none of the cases ever used content-box anywhere. I think I'll bring this up with my team. On another note, do you think "stretch" size will even make border-box unnecessary?

Totally! It probably depends some on the things you're doing, but even efficient use of grid/flex right now, you might find that it's rarely (if ever) needed.
